Bimmercircuit Equal Length Exhaust

Was looking at youtube videos and saw a video on a "new" and "true" equal length exhaust.

Has anyone heard anything about it?

I had thoughts about the AA EL midpipe and it's harmonics and engineering, and then stumbled upon this video. The video doesn't really give much, though.

With how much different exhausts can sound between rev ranges, modes, and camera/microphones, I'd like to hear some other clips of it.

Hi - We just came across this video here. Thank you for finding it.

The "teaser" video gave a full range of sound through the RPM band. We are currently in the process of making a full review of the videos, including the irrelevant sound clips of an FI engine revving in neutral lol

Please contact us at contact@bimmercircuit.com if you have my questions!

3- Actual engineering and product development was done to produce this sound, increase performance, and decrease weight.

Ours is straight piped as well, but we don't think we ruined ours

We'll love to show you when we're done with it. If you're local to the Los Angeles area, come on by the shop, we can take you for a drive.

If I wasn’t already married to my AWE switchpath and aa equal length, I’d be seriously considering this full system.

We ran this setup as well, look into our midpipe with your AWE, we think you'll be very very happy with what you hear.

We would like to clarify your ""'s....

New: Yes. We received our patent pending from the US patent office late fall of 2022. It is new and unique enough they granted us patent pending, considering AA has an "equal length" as well, ours is far different, for both utility, sound, and design.

True: Yes. We have the ONLY true equal length exhaust on the market. No other company can claim they do, because they are not equal after they merge the exhaust banks. Our system is equalized 3 feet sooner than AA, and we are equal length after the merger back to the inlets of our "mufflers". The BC Equal Length is the only unit which actually equalized both banks, from the engine, to the "mufflers".

For that kind of $$ I would need to see a same day dyno of before/after for any hp/trq gains or losses.

I think the knock on the AA setup was a loss of torque. Could be wrong about that, just going off memory.

How does this system differentiate from the AA Equal length that seems to be so popular?

USA made - sorry but super questionable because generally that’s means made cheaply in China then packaged with a logo. European products have been 10x better..
Quality of material?? Just say the material.
Actual engineering then show us what you flipping did lmao.
I don’t think it sounds as good as stock mid pipe with Mpe but your video wasn’t so clear either 🤣
